NOYAFA JMS13 Household PM2.5 Humidity Monitor Rechargeable LCD Digital Air Quality TVOCHCHO Formaldehyde Tester PM2.5 Monitor Desktop Hygrometer Formaldehyde Air Quality Analyzer for Hom

The air quality can detect ambient PM2.5 HCHO TVOC and humidity through a dedicated sensor module and has a big LCD display screen to display data. In addition according to the quality of the test object there is a corresponding grade indication. When HCHO exceeds the standard seriously there will be a buzzer indication. Really a good helper for family living environment detection. Features: Multifunctional Air Quality : it can test the PM2.5 HCHOTVOC and humidity real-time all-round detection detect the air quality anytime and anywhere. Mie Scattering Acceleration Measurement: sensitive detection of PM2.5 pollution index more accurate detection of small particles. and Humidity Compensation Calibration: through the principle of semiconductor humidity sensor and thermal sensor the and humidity change can be accurately measured to ensure more accurate formaldehyde detection results. Independent Sensor AI Intelligent Computing: semiconductor TVOC detection module real-time display of formaldehyde concentration per cubic meter TVOC content etc. The Intelligent Calibration and Detection of SEN+ Algorithm are Accurate: the high-performance chip algorithm has -interference high sensitivity fast operation speed and more accurate and stable data. Convective Air Holes and Bracket Design: 3D convection hole design close to the sensor real-time air circulation convection for more accurate detection.
